Parker RK3B2 Valve

The Parker RK3B2 is a heavy-duty solenoid coil replacement engineered for high-performance fluid control in industrial refrigeration and HVAC systems. Designed for 24V/60Hz AC applications, this 22-watt coil provides the necessary electromagnetic force for reliable valve actuation under demanding thermal loads. This Parker solenoid coil features a durable junction box configuration with 6-inch lead wires, ensuring secure electrical terminations and simplified field installation. Built to withstand the rigors of continuous duty cycles, the RK3B2 is compatible with a wide range of Parker and Refrigerating Specialties (R/S) valve bodies, including the popular S4A, S5A, and S6A series. When diagnosing refrigeration valve troubleshooting issues, verifying coil resistance and voltage compatibility is critical; this solenoid coil 24V assembly ensures consistent plunger lift and seating, preventing system short-cycling and maintaining precise refrigerant flow control in critical cooling applications.

• OEM Compatibility: Precision-fit for Parker Hannifin and R/S division industrial solenoid valves.
• High Thermal Rating: 22W power consumption rated for continuous operation without excessive heat degradation.
• Integrated Junction Box: Provides robust protection for electrical connections in high-vibration environments.
• Flexible Installation: 6-inch leads allow for easy splicing or terminal block integration within the housing.

What is the primary cause of coil burnout on an RK3B2?
Burnout typically occurs due to overvoltage, incorrect frequency (Hz), or mechanical obstruction in the valve body preventing the plunger from seating, which increases current draw beyond rated capacity.

Can this coil be used on DC circuits?
No, the RK3B2 is specifically rated for 24V/60Hz AC. Utilizing this coil on a DC circuit will result in immediate failure or insufficient magnetic field strength to actuate the valve.

Is the junction box required for operation?
The junction box provides environmental protection and a secure termination point; it is essential for meeting electrical codes and protecting leads from moisture and physical damage in industrial settings.
